Application filed August 20,1904. Serial No. 221,508.

To rtll whont it may concern:

Be it known that 1, JAMES VEST, a citizen of the United States, residingat Seattle, in the county of King, State of \Vashington, have inventedcertain new and useful Improvements in Lawn-\iowcr Attachments; and Idohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to lawn-mowers, and more particularly toattachments therefor, and has for its object to provide an attachmentapplicable to any lawn-mower which may be used for trimming the edges oflawns along walks or driveways or in similar places.

A further object is to provide a device of this nature which will besimple in construction and which may be manufactured at a low figure.

Other objects and advantages will be apparent from the followingdescription, and it will be understood that modifications of thespecific construction shown may be made and any suitable materials maybe used without departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in whichlike characters of reference indicate similar parts in the severalviews-Figure 1 is a side elevation of a lawnmower, showing the presentinvention attached thereto. Fig. 2 is a perspective view of theattachment removed from the mower. Fig. 3 is a side elevation of thedevice attached to a mower and showing it in the position it occupieswhen the mower is in use. Fig. 4 is a perspective view of a modifiedform of the invention and illustrating a portion of a mower to which itis attached.

Referring now to the drawings, the present invention comprises a casting5, including a flat plate 6, somewhat elongated and having a U-shapednotch 7 in one of its edges. Projecting from one face of the plate 6 andformed integral therewith is one member 8 of a clamp 9, this memberbeing in the form of a plate which extends longitudinally of the plate 6and which is provided with a convolution 10, the concave surface ofwhich lies flush with the curved inner end of the notch 7. Disposedagainst the member 8 is the second member 11 of the clamp, which is inthe form of a separate plate having a transverse convolution 12extending in the opposite direction to the convolution 10 and coincidingtherewith to form a substantially cylindrical passage 13, the twomembers of the clamp being held together by bolts 14.

Between the notch 7 and the forward end 15 of the plate 6 and at theopposite side of the plate from the clamp 9 the plate 6 is pro videdwith a pair of spaced ribs 16, extending diagonally thereacross, andthese ribs are inclined transversely toward each other to form'adovetail groove 17, in which there is slid-ably mounted a knife-blade18. Extending longitudinally and centrally of the groove 17 there is aslot 19, formed through the plate 6, and in this slot there is slidablyengaged a bolt 20, which is passed through an opening 21 in the blade18, and this bolt is provided with a nut 22, which may be operated toclamp the blade against movement in the groove 17 As illustrated, thecutting edge of the blade 18 lies away from the notch 7. I At theopposite side of the notch 7 from the blade 18 the plate 6 is providedwith acircular portion 23 at its ends, having radially-extendingcorrugations 2 1 and a central perforation 25. An arm 26 is providedhaving a circular end portion 27, and this end portion is also providedwith a central perforation 28 and radial convolutions 29, theperforations 25 and 28 being disposed in alinement with each other forthe reception of a bolt 30, which may be operated to clamp the twocircular portions together, the corrugations preventing movement of thetwo portions with respect to each other.

In use the attachment is disposed upon a lawn-mower A with the uppertransverse brace-rod 31 thereof engaged in the notch 7 and in thepassage 13 between the members of the clamp 9, the bolts 14: beingscrewed up to hold the attachment in position. The lawnmower includesthe usual cutting-blades B. The device is so disposed that the blade 18projects upwardly and forwardly and the arm 26 is adjusted to extendupwardly and rearwardly and in the path of movement of the handle 32 ofthe lawn-mowerupon its pivotal connection with the remainder of theimplement. This arrangement of the attachment does not interfere withthe use of the lawnmower in the usual manner, and when the attachment isto be used the lawn-mower is inverted, as is usual when the implement isbeing transferred from place to place, the ratchet mechanism within thewheels preventing rotation of the cutting-blades B, and when this isdone the handle 32 comes into engagement with thearm 26, as illustratedin Fig. 1,

and the blade 18 is brought into position to cut the grass, as mentionedabove. By reason of the adjustability of the arm. 26 and the clamp 9 theattachment may be used in connection with different-sized lawn-mowers.

In Fig. 4 there is shown a modification in which the plate 6 is providedwith a lateral extension 33, which projects beyond one of the wheels ofthelawn-mower, and at the end of this extension 32 there is an extension34, to which the blade 18 is attached in the manner already described,the blade being thus brought to a point outwardly of the wheel of theimplement so that the implement may run entirely on the walk or drivewaywhen the grass is being cut by the blade.

\Vhat is claimed is 1. The combination with a lawn-mower includingsupporting-wheels, a grass-cutting blade connected with the wheels, anda bracerod, said lawn-mower being movable to bring its grass-cuttingblade into and out of operative position, of an edge-cutting bladeconnected with the brace-rod and disposed to lie in operative positionwhen the grass-cutting blade is in inoperative position and to lie ininoperative position when the grass-cutting blade is in operativeposition.

2. The combination with a lawn-mower, of an edge-trimming attachmentremovably attached thereto, said attachment including a blade arrangedto lie in inoperative position when the lawn-mower is in use, and to liein operative position when the lawn-mower is inverted, and an armarranged for engagement by the handle of the lawn-mower when the latteris inverted to hold the blade in engagement with the grass to be out.

3. An edge-trimming attachment for lawnmowers comprising a platearranged for attachment to a lawn-mower, a blade adjustably connected tothe plate, and an arm adjustably connected to the plate, said arm beingarranged for engagement by the handle of a lawn-mower when the latter isinverted to hold the blade in operative position.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES WEST.
